This invention relates to brooder stoves and particularly to brooderstoveshaving a detachable hover which is shiftable sofas to raise thehover or lower the hover under certain changes and conditions. n Thegeneral object of the inventionis to improve certain details disclosedin pending application-Serial No. 193,836, filed on the 24th day of.May, 1927, issued June 18, 13 1929, as Patent No. 1,717,851. 8 r

In that application I have shown a brooder stove which includes an ashpit, a combustion chamber,'a magazine, and a smoke flue, the

flue having a check draft damper and ther mostat-ic means forcoordinately controlling the action of the two dampers. v

More specifically, one of the objects of the present invention isto'provide' a water chamberexterior to the magazine and between the"ends of which the smoke flue passes, whereby to provide a means forsupporting the hover in a vertically shiftable position and the wateracting to retain a more uniform tem- 'perature within the brooder roomand furn1sh moisture to the air in the brooder room,

this water chamber further acting to restrain the dry heatordinarilyescaping from the magazine walls.

Another object is to so construct the stove that a space is left betweenthe top of the combustion chamber and the lower end of the water chamberwhereby the heat from the v upon the water chamber surrounding themagazine. p,

Other-objects will appear in the course of the following description. rMy invention is illustrated in the accompanying drawings wherein 1Figure 1 is' a vertical sectional view through a brooder stoveconstructed in ac cordance with my invention;

Figure 4 is a face view of the detachable wall of the smoke flue;

water chamber of the brooder stove showing the connection of a drinkingpan.

Referring to Fig. 1, itwill'be seen that the stove comprises the ash pit"10, the combustion chamber section 11, the grate 12, the supportingbrackets 13'therefor, 'an'upper section 14 for the combustion chamber, alower 'magazine section 15 forming part of or carried by the section 14,and an upper magazine section 16 which carries upon it the water chamber17 which is concentric to the section The section 11 issupported'uponthetop ported upon the top of the section 11.- The"section 16' is supportedupon the upper end of the lower wall section 15of the magazine. The ash pit is providedwiththe air inletopening 18 andthe upper end of :the' magazine is normally-closed by a cover 19.v Thewater jacket or chamber17 has a filling opening provided with a cover20.

As Wlll be seen from Fig. 2, the magazine of the section 10 .and thesection 14: is sup is circular in cross section and surrounding themagazine is the water chamber 17. This extends nearly aroundthe magazinebut terminates in the vertical end walls 21 defining a smoke flue 22.This smoke flue extends down to the lower end of the magazine section 15and this magazine section carries upon it the circularly extendingbaflie wall 23. i The walls 21 terminate in spaced relation'to thisbattle wall so that an opening 24 is left through which ,theproducts ofcombustion passing upward fromthe combustion chamher 11 may pass throughtothe smoke chamber 22'. The upperend'of the smoke flues isprovided witha nipple 2 5for theattach ment of a smoke pipe.

' The front wall of the smoke flue isconstituted by a removable plate 26and by a wall 27 formed integral with the section 15 of the magazine andextending upward from the outer wall 11. The removable wall 26 has anaperture 26 at its upper end on the inside of which is mounted a checkdraft damper 28. This check draft damper is detachably mounted uponpivots at its upper end upon the upper end of the inside face of thewall 26 and has an outwardly projecting arm 29 to which the wire or rod30 is connected.

The draft damper 31, pivoted at 32 by means of a plate 38, is attachedto the wall of the ash pit 10 and is provided with an outwardlyprojecting eye to which the lower end of the rod 30 is connected by ahook. This rod 30 is connected to a thermostat as will be later stated.

The outer face of the outer wall of the water chamber 17 is formed witha plural ity of steps or ledges 34. It will be seen that the stoveincluding this water chamber is preferably tapered upward.

The hover 35 is annular in form and provided with a ring 36, and thehover is preferably of sheet iron and its riveted or otherwise attachedto this ring and the hover is preferably provided with a ventilatoropening 37 having a damper 88. Adapted to fit upon the several steps 34,except the lower step of the series which is of sufficiently largediameter to engage with thering 36, is a ring 39 which is cut away at 40so as to fit over the front wall 26 and is cut away at 41 to permit thepassage of the wire or rod 30. The underface of this ring 39 is providedwith the lugs ,42 constituting brackets, as it were. lVhen the hover isin its lowest position, it rests upon the flange 423 at the base of thewater chamber 17. I If it is desired to elevate the hover, one of therings 39 is placed upon the proper step 34 and the ring 36 forming aninner margin of the hover is engaged with this ring 39.' r

It will be seen from Fig. 5, that the water chamber may be provided atits upper and lower ends with the outwardly extending circulating pipeslei which may lead to a water heater whereby the drinking water for thechicks may be warmed. Any number of these drinking water heaters may beconnected up with the water chamber 17.

lVith the construction which has been illustrated, the water jacketsurrounding the magazine serves a three-fold purpose. Its outer surfaceprovides a very simple means for supporting the hover in verticallyadjustedposition. The heated Water within the water jacket or chamber 17derives its heat from contact with the magazine walls and serves tosecure or maintain a more uniform temperature in the brooder than isotherwise possible as it will remain hot for a considerable time afterbecoming heated.

Furthermore, the slight amount of steam or vapor generated by this waterheater, furnishes moisture to the air in the brooder, thus preventingthis air from becoming too dry. This secures for the chicks a soft moistheat instead of a dry harsh heat. The water within the water chamberbecomes heated to the proper degree a short time after the stove isfired. N

Then the hover 35 is at its lowest posi tion, the water jacket or waterchamber 17 serves to restrain the dry heat otherwise escaping from themagazine walls. Under normal circumstances, the fuel within the magazinewill tend to back-fire or heat up. Considerable heat will be radiatedoutward from the walls of the magazine. This heat is modified thereforeby the water contained within the water chamber 17. At the same time acertain amount of heat is radiated from the space between the upper wallof the combustion chamber 14 and the lower wall of the water chamber 17.The cover or wall 26 of the combustion chamber is removable for thereason that it carries at its upper end the check draft damper and asthis damper is hinged on the inside it is-necessary to have anopportunity to place the bearing surface of the damper. This can beeasily done if this wall 26 is removable.

Furthermore, by making this wall 26 removable, it permits the smoke fineto be cleaned out. It will be seen that the cover or wall 26 engaging inthe offset opening 40 of the ring 39, holds anyone of the rings 39 fromturning around the magazine. The hover, however, may be rotated uponthis supporting ring 39 as desired.

I do not wish to be limited to any specific vmeans for connecting orholding the sec- I tions together, but I have illustrated bolts 45holding the section 11 onto section 10 and bolts 46 extending upwardfrom the upper end of the section 11 to the flange 43 of the uppermagazine section and water chamber.

Obviously these bolts might be arranged in a different manner withoutdeparting from the spirit of-the invention.

The thermostat 47 is of any usual or suitable type, but I haveillustrated this theri mostat diagrammatically. It is mounted upon abracket 48 and operates the arm 49 which is connected to rod 80. WVhenthe heat increases beyond a predetermined point the thermostat pushesthe arm 49 down, which of course, closes the draft damper 31 and opensthe check draft damper 28. When the heat decreases beyond apredetermined point, the thermostat moves in an-opposite directionlifting the arm 4-9 and causing the opening of the draft damper and theclosing of the check draft damper. I do not wish to be limited to thisas I have stated before, to any particular construction of thisthermostatic means.

As shown in Fig. l, the rod 30 passes loosely through the eye on thedraft damper 31 so 7 that rod 30 may be raised and the check draftdamper closed before the draft damper opens and vice versa, the draftdamper may close before the check draft damper opens.
